When it's time to replace your old decaying foam seal, go with our reproduction weatherstrip retainer foam roll with peel off adhesive. Goes between the roof and door / window channel.
These are not technically manufactured to fit the Cougar / Mustang, however these are very close to the originals and come from the manufacturer in a roll that is 4' X 1" X 1/8". One roll is more than enough to do one side, but you will need 2 rolls to do both sides.
